"In our judgment, these authorities demonstrate that the prosecution must in a case concerning escape prove four things i) that the defendant was in custody; ii) that the defendant knew that he was in custody (or at least was reckless as to whether he was or not); iii) that the custody was lawful; and iv) that the defendant intentionally escaped from that lawful custody."
"We are ... concerned that the jury were not in any sense adequately instructed on the issues. Little or no controversy arose from the initial arrest (and the consequent lawful custody) or indeed from the final 'escape' (in the sense of eluding any continuing custody). What was in issue was the question of the continuity of the custody and the appellant's knowledge of it. 28. Although the judge made considerable play of what might be assumed to have happened on PC Mitchell's arrival, the jury's task in assessing continuity was potentially impeded by the absence of any evidence from the police officer who took the appellant to hospital and who was later said to have effected the handover to him (a handover which on any view was relatively informal). There was a live issue as to whether the appellant was still subject to sufficient direct control at the time of his escape two hours later. By the same token, there was an issue as to the appellant's knowledge since his case was that, whilst he saw the first officer leave, he never saw the second officer arrive and could find no substitute."
"I agree with Mr Spackman's submission that whether a person can be said to be in custody at any particular time is a question of fact to be decided by reference to the circumstances of each individual case. 'Custody' is an ordinary English word, which should be given its ordinary and natural meaning subject, of course, to any special meaning given to it by statute. In the Shorter Oxford English Dictionary the word 'custody' is defined in the following terms, amongst others: 'Confinement, imprisonment, durance'. 20. As it seems to me, for a person to be in custody, his liberty must be subject to such constraint or restriction that he can be said to be confined by another in the sense that the person's immediate freedom of movement is under the direct control of another. Whether that is so in any particular case will depend on the facts of that case."
"I agree that, from the facts as found, we can infer that, at the time when he ran off, the appellant was under restraint, in that he was at court in company with members of the youth offending team, who had the power, as he knew, if necessary, to restrain him. His liberty was thus restricted and he was therefore in custody."
"A prisoner shall be deemed to be in legal custody while he is confined in or is being taken to or from any prison and while he is working, or is for any other reason, outside the prison in the custody or under the control of an officer of the prison and while he is being taken to any place to which he is required or authorised by or under this Act... to be taken, or is kept in custody in pursuance of any such requirement..."
